Answer:
Option 1 and Option 3 are true.
Step-by-step explanation:
Given: Two triangles have equal area.
Area of triangle is depend on base and height because area of triangle is half base and height.
If two triangle has same base and height their area must be same.
Option 1 is true. The triangles have equal base lengths and equal heights.
If two triangles are congruent then their base and height equal by CPCTE property of concurrency. Base and height of congruent triangle are equal.
Option 3 is true. The triangles are congruent.

Answer:
A
Step-by-step explanation:
This is exponential decay; the height of the ball is decreasing exponentially with each successive drop. It's not going down at a steady rate. If it was, this would be linear. But gravity doesn't work on things that way. If the ball was thrown up into the air, it would be parabolic; if the ball is dropped, the bounces are exponentially dropping in height. The form of this equation is
, or in our case:
, where
a is the initial height of the ball and
b is the decimal amount the bounce decreases each time. For us:
a = 1.5 and
b = .74
Filling in,
If ww want the height of the 6th bounce, n = 6. Filling that into the equation we already wrote for our model:
which of course simplifies to
which simplifies to
So the height of the ball is that product.
A(6) = .33 cm
A is your answer
